Malicious code in react-paginate-v5 (npm)

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

Its package.json declares a preinstall lifecycle script that runs `nslookup dep-confusion-poc.2chsn9exkdupkr3cxed7vp7sk.canarytokens.com`, which fires automatically on `npm install` and emits a DNS query from the installer's resolver to an attacker/researcher-controlled canary subdomain. The subdomain label (`dep-confusion-poc`) self-identifies the operation as a dependency-confusion test. The DNS lookup confirms successful installation to the operator of the canary token, identifying hosts and networks where an internal package name was shadowed by this public squat. While the beacon itself only exfiltrates the fact of installation plus resolver metadata, the same install-time execution primitive can carry any shell command, and the package has no legitimate functionality.
